DOI: 10.1201/9781003161318-26

Chemical encapsulation is a type of encapsulation method in which chemical reactions such as polymerization or polycondensation are involved in the encapsulation process.

Interfacial polymerization, in situ polymerization, emulsion polymerization, and matrix polymerization are the most common chemical encapsulation methods.

  • Interfacial polymerization  Interfacial polymerization was developed by Morgan and coworkers in 1959. In 1964, this process was employed to prepare nylon microcapsules by Chang. This process includes two reactants dissolved in a pair of immiscible liquids, and the polymerization takes place at the interface to form a continuous film and thus the microcapsule (Figure ...
